外墙防火复合板表面变形和脱色的原因

(1) 复合板本身质量问题。外墙复合板厚度应该达到4 毫米, 漆面要用能抗老化的氟碳树脂(PVDF) 涂层。而一些施工单位片面追 求利润,往往把内墙板用到外墙工程中,由于厚度不够极易产生变形, 非氟碳树脂(PVDF) 涂层而导致脱色;
(1) the quality of the composite plate itself. Exterior wall composite plate thickness should reach 4 mm, with fluorocarbon resin paint can anti aging coating (PVDF). And some construction units one-sided pursuit of profit, often the interior wall panels used in external wall engineering, due to the thickness is not very easy to produce deformation, non fluorocarbon resin (PVDF) coating and lead to decolorization;
(2) 施工工艺选择不当。外墙防火复合板必须采用干挂施工工艺。有些设计人员在设计图中只注明为A2级防火复合板饰面而未标施工做法,建设单位和施工单位从工程造价和节省成本的角度选择了内墙板施工的粘贴工艺.
(2) improper selection of construction technology. The dry hanging construction technology must be used in the exterior wall fireproof composite board. Some designers in the design is only indicated for A2 Level fireproof composite board finishes without standard construction practices, the construction units and construction units from the paste technology of engineering cost and save cost point within the selected panel construction.

将防火复合板粘贴在基层板材上, 基层材料主要是高密度板、木工板之类。这类材料在室外使用时,其 使用寿命是很脆弱的,经过风吹、日晒、雨淋后必然会产生变形,基 层材料的变形导致复合板面层的起鼓,再加上复合板和基层木工板之 间线膨胀系数的不同,粘贴将不再牢固可靠,进而发生脱落,影响建 筑物美观。
The fireproof composite board is pasted on the base plate, and the base material is mainly high density board, wood board and the like. This kind of material in outdoor use, its service life is very fragile, through the wind, sun, rain will produce deformation, deformation of base material layer lead to composite board surface of the drum, plus composite plate and basic carpentry plate between the line expansion coefficient of different paste will no longer be solid and reliable, and then fall off, affecting building building appearance.
